Who's there?

At Many-to-Many, Ross Mayfield reports that Clay Shirky and danah boyd have been thinking about "the lingering questions in our field", viz. the field of social software. I was a bit surprised to see that

How can communities support veterans going off topic together and newcomers seeking topical information and connections?

still qualifies as a 'lingering question'; I distinctly remember being involved in thrashing this one out, together with Clay, the best part of nine years ago. But this was the one that really caught my eye, if you'll pardon the expression:

What level of visual representation of the body is necessary to trigger mirror neurons?

a woman in a nursing home outside Boston is sad. Her son has broken off his relationship with her. Her nursing home is taking part in a study I am conducting on robotics for the elderly. I am recording the woman’s reactions as she sits with the robot Paro, a seal-like creature advertised as the first ‘therapeutic robot’ for its ostensibly positive effects on the ill, the elderly and the emotionally troubled. Paro is able to make eye contact by sensing the direction a human voice is coming from; it is sensitive to touch, and has ‘states of mind’ that are affected by how it is treated – for example, it can sense whether it is being stroked gently or more aggressively. In this session with Paro, the woman, depressed because of her son’s abandonment, comes to believe that the robot is depressed as well. She turns to Paro, strokes him and says: ‘Yes, you’re sad, aren’t you. It’s tough out there. Yes, it’s hard.’ And then she pets the robot once again, attempting to provide it with comfort. And in so doing, she tries to comfort herself.

What are we to make of this transaction? When I talk to others about it, their first associations are usually with their pets and the comfort they provide. I don’t know whether a pet could feel or smell or intuit some understanding of what it might mean to be with an old woman whose son has chosen not to see her anymore. But I do know that Paro understood nothing. The woman’s sense of being understood was based on the ability of computational objects like Paro – ‘relational artefacts’, I call them – to convince their users that they are in a relationship by pushing certain ‘Darwinian’ buttons (making eye contact, for example) that cause people to respond as though they were in relationship.
